Specification of Letters Patent.

Application filed April 1, 1903. Serial No. $24,636.

To all whom "it ma 3 concern Be it known that 1 Srnnnr L. Bnown', a itizen of the United States, residing at Mainaroneck, in the county of ivestchcster and State of New York, have invented certain new and useful lin rovemenis in (ame- Leads, of which the ioliowing is a specification.

My invention relates to a lead for setting glass in windows commonly known as came lead. Necessarily tho-lead for. this purpose is very'pliable in order that it may be bent to conform to the (DHlZOllYOl' the sections of glass composing the window, and it .is essential to the rigidity and security of the window that provision be made to rcsistany lateral iorce, such as wind pressure, which may be applied to it. With plain leads'this is acconiplished'by stay bars set intothe sash and to which the leads are fastened by wire or solder. It has alsolbeen proposed to embed in the heart,during the process of manufacture of the lead, a stiil'euing core of tinned iron or similarmaterial. This form inpractioe, however, has been found open to the serious objection that itis impossible to secure a perfect joint between intersecting leads. Thisis due to the fact that the still'ening core is com )letely embedded in the heart and so eoncezdcd'that the workmen cannot get at the exposed end o't' the core which is torccd between the caps of the intersected or continuous section to properly solder the joint.

and it frequently happens, therei ore, that the joints give way, resulting in a weakening of the window to such extent that it bulges and is often seriously damaged. As leaded windows in many instances can be made only at great cost, any means tending to greater security during the process of making and after being placed in position is of advantage. in the art.

The objects of my invention are to make a lead which will enable'the assemblage: of the window sections with the facility incident to a plain lead and by which the leads after assemblage may be reint reed or strengthened and a perfect joint'e'llccted between intersecting leads.

These objects I accomplish by grooving or channeling the lead ina longi-. tudinal direction along one or both of the caps, the groove extending into the heart to any depth desired.

My invention relates primarily to the,

grooved lend itself as it is made and sold as f groove 0.

an article of manufacture distinct from the strengthening rib, the latter, in practice, be-

ing laid into the groove alter the window has been loaded either wholly or partially; and

to the construction of the joint between in-- tcrsecting leads by which I am enabled to extend the rib beyond the end of its lead so as to abut against the side of the rib-of an intersected lead and to solder the same thereto to make. a rigid joint.

The invention will be understood by reference to the following description taken in connection with the accompanying drawings in which Figure l is a plan view of a portion of a loaded window; Fig. 2 a perspective view of the strengthcningrib Fig. 3 a similar view of one embodiment of my invention; Fig. 4 a

top view of two intersecting leads to illustrate the manner oi oining-them; Fig. 5 a

longitudinal section on the plane of the line 5 -5 of Fig. 4; and Figs; 6 and 7 perspective" views of modified forms of leads.

Similar reference numerals-indicate similar parts in'thc several views.

in the embodiment of my invention-illustrated in Figs. 3 -4 and 5 the lead may be compared with a plain lead having a central longitudinal groove or channel extending through the upper cap and into the heart to any depth desired. That is, such lead comprises a continuous lower cap 1, a heart 2, and a sectional upper ca) consisting o the flanges 3 3 extciuling laterally fron the heart, theraps forming side grooves 4 to receive the glass as in aplain lead. A longitudinal groove or channel 5 extends through the upper cap and into the-heart, preferably to about the depth shown in Fig.3. it is preferred not to extend the groove 5 entirely to the-lower ea 3 '1 as that wonldresult in weakening the end to too great an extent. it is necessary that sufficient body should be given to the heart to prevent: the collapse of the lead after it is manufactured and also in its use: by the workmeniin leading windows. This groove runs along'the median line of the cap: and is open throughout its length, and in eli'ect constitutes a pocket adapted to receive L I astrengthening rib 6 in the manner presently 1 to he described. scribed lead instead of having a continuous -upper cap and a solid heart as in a In other words, the de I clam loan, has such. cap divided longitudina ly by the be lead made by me is an into-- joints.

gral structure and may be made in a press'of nown type provided with dies suitablefor the purpose.

One of the advantages of'the lead above described lies in the facility with which it may be strengthened and the joints made secure. 'In its use the window is leaded either partially'or wholly in the same manner as a plain lead is used. Before soldering, the strengthening ribs 6, which may be of tinned iron, steel; brass or similar material, are laid into' the grooves 5. Thus in Fig. 1 the rib may be laid in the binding strips 7 and 8 in continuous lengths equal to the lengths of the leads. ()n the panel work, however, the ribs 6.are cut in such lengths as required by the conditions met with at the Thus in the interior vertical and horizontal strips the ribs 6 are longer than. the corresponding leads and project beyond. the ends of the lead in order to abut against the rib of the intersecting lead to which it is soldered. This manner of joining two leads will more clearly appear byrel'erence to .Fig.

4 in which'the lead a is intersected by the leads I) and c. In lead 'a the rib 6 is continuous across the intersection as in strip 9 of Fig. 1, leads I) and 0, corresponding respectively, for the purpose of illustration, to the strips 10 and 11. In order, therefore, to solder the ribs together, the flanges 33, constituting the upper cap of lead a, and the heart of said lead, are cut through, transversely to the walls of groove 5 in lead and the cut sections removed to provide an opening to receive the ends of the ribs-'6' to be placed in grooves 5 of leads I) and c. I In the I former the rib 6 has been placed inposition and its projecting end abutted against and soldered to the side of rib 6 ol leadn; The lead 0 is shown as abutting against the side of lead a, the portion to be cut out of lead a to receive the rib 6 of lead 0 being indicated in dotted lines. Upon the completion of the window solder is flowed over the lead in the usual manner,

In Fig. 6 I have shown the additional groove as T-shaped in section, and the corres )ondingly shaped iii) 13, the head of which is ush with the top of the upper cap.

Fig. 7 illustrates a further modi'lication in which both caps are grooved. The upper cap iStllB same as shown in Fig. 3. The lower cap 1 is divided by a similar longitudinal groove adapted to receive ajstrcngth-cw ingrib 6. The heart 2 in this form consists of vertical, websjoining the caps and a horizontal connecting web substantially midway betweenthe caps. I

From the foregoing description it Will be seen that my invention provides means for strengthening the leads in an. entirely novcl manner, and one which possesses marked utility in that the ribs are not inserted until the leads have been bent-into the form required by the glass sections. By abutting the ribs of intersecting sections so that they may be soldered together a practically rigid joint may be made, this work being greatly facilitated by the fact that the groove in the lead adapted to receive the strengthening rib is open and the rib itself is at all times within access of the workmein The window can thus be made secure at all joints between the leads and is thus able to Withstand lateral pressure without danger of breaking.

What I claim and desire to secure by Lettors Patent is 1. A came load comprising caps forming side grooves to receive the glass, one of said caps being solid and integral with the heart, and the other of said caps having an open longitudinalgroovc for the purpose described.

2. A came load comprising caps forming side grooves to receive the'glass, one ol said caps being solid and integral with the heart, and the otherof said caps having an open longitudinal groove extending into the heart for the purpose described.

3. A came lead comprising caps forming side grooves to receive the glass, one of said caps being solid and integral with the heart, and the other of .said caps having an open longitudinal groove extending into the heart, and a still'cning rib seated in said igroove.

4. A came lead comprising caps forming side grooves to receive the glass, and an ad-'' dltional T-shapod open longitudinal groove opening in the cap leading to the ccntrab groovo'thm'cin, and the rib ol' the intersect ing lcad projecting beyond the end thereof and into said transverseopening and abutting against the rib ol' the continuous lead.

in testimony whereof I have hereunto signed my name in the scribingwitnesses.
